BOLT-CLIPPER.

To a/ZZ whom it may concern:

.Be it known that I, ARTHUR L..MOORE, a

citizen of the United States of America, and.

a resident of'S ringfield, in the county of Hampden and tate of Massachusetts, have v invented certain new and usefulIm rovements in Bolt-Clippers, of which the ollowing is a full, clear, and exact description.

This invention relates to improvements in bolt-cli pers of the class comprising com poundevers, one pair thereof constituting the handle or operating members and the Ether carrying the cutters or bolt-clipping The particular object of this invention is to provide a clipper having adjustablymov.

able members or levers for positioning the cutter-levers to compensate for wear or grind.-

v ing away of the cutters and having come bined therewith means not only for moving the adj usting-levers with great powerand for exactness of adjustment, but for also eifec-- tually maintaining the parts located in their adjusted relations, and an important object also attained is the production of a clipper having the cap abilities stated and constituted by a reduced number of cheaply and simply constructed and easily assem'bled parts; and the invention consists in the constructions and combinations or arrangements of parts, all substantially as hereinafter fully described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a side view of the, resent improved boltclipper, portions of t e long handles of which are represented as broken away and the portions of said. handles shown as broken out and in vertical section. Fig. 2 is a perspective view of certain parts of a bolt-clipper comprised in this invention as in separated relations to each other.

Similar characters of reference indicate corres onding parts in both of the views.

In t e drawings, A A represent the handles, which are of considerable length and united at their forward angularly-turned extremities by a hinge-pivot a. A semicircular sidewise-open recess or depression B is formed in each handle A adjacent the hinge-pivot a, such recess being the counter art in circumferential dimension ofthe shou dered interme-' diate portion of each of the pair .of adjusting" levers O. The adjusting-levers C, which are pivotallyheld in osition in the recesses B by the pivot-bolts b, have each on one arm 0 thereof the ear-lugs 0', between which the reduced extremities of the free ends of the cutting-jaw levers D are engaged and held by the bolts (1. The cutting j aw levers D are held inpivoted relations to each other by the usual side links E, which are pivotally connected thereto bytheir pivot-bolts e e. The arms G endwise opp'ositeto those above mentioned. of the adjusting-levers C extend into the cavities H, which are formed in the handles and extend thereinto from the handle depression B in a direction toward the free ends of said handles a considerable distance, as shown by a reference to Fig. '1. The free ends of the arms G of adjusting-levers are constructed with the gear-teeth 9 arranged in radial relation to the pivot-bolts b, thereby constituting segmental worm-gears g.

'At a point in each handle-cavity H near its closed end is located a vertically suppora ed screw-threaded. bolt or worm 1, its shouldered end portions h and h having bearings in the outer and inner edge walls of the said cavity in the handle; The shouldered end h enters and is supported in the round hole 1' of the handle, and the shouldered end h'has a bearing ina nut K,"whi'ch nut has a screw enga ement within the threaded hole 7c of the hand e, and this hole 7: is of a diameter equal to that or larger than that of the worm I, thus permitting the positioning of the worm I'in the handle-cavity H, whereby the subsequent positioning of the adjusting-lever 0 brings the segmental gear G-of the same into mesh with the worm I.

A squared portion t of the shouldered bearing end h of the worm I is adapted to be engaged and turnedbya wrench, whereby the rotation of the worm I rocks the adjustinglever C on its pivot b by its engagement therewith of'the'se'gmental gear G, to the end that the cutting-j aw levers. D, having the cuttingjaws D thereon, are correspondingly moved or adjusted to the handles A through the pivot engagement of adjusting-lever arm c Having thus described my invention, what I claim, and desire to secure by Letters Patent, is I 1. In a bolt-clipper of the class indicated, the combination With the handle-levers pivotally jointed at their forward extremities, the cutter-levers and adjusting-levers jointed to the cutter-levers and intermediately pivotally jointed to the handle-levers adjacent the handle-lever hingejoint, and having their rearwardly-extended arms formed with worm-segments at their ends, and worms supported for rotary movement on, and arranged transversely of the handle-levers, in engagement with the wormsegments, and having provisions for imparting their rotational movements to the adjusting-levers.

2. In a bolt-clipper of the character de scribed, the combination with the handle-levers pivotally jointed at their forward extremities, and having a sidewise-opening recess B with partially-eircular edge walls and said handles having longitudinally-extending cavities H, H, opening to said recesses, of the cutter-levers D D and the adjustingle vers C C having the thickened and rounded intermediate portions fitted in said recesses B, and pivotally connected thereat with the handlelevers, and having their arms G rearwardly extending into said handle-cavities and provided at their ends with the wormsegments g, and the worms I I journaled within the walls of the handle-levers, traversing the cavities therein, and in engagement with the worm-segments of the adjustinglevers.

3. In a bolt-clipper of the character de scribed, the combination with the handle-levers pivotally jointed at their forward extremities, and having sidewise-opening recesses B with partially-circular edge walls and said handles having longitudinally-extending cavities H, H, opening to said recesses, and constructed with the journal-hole at one edge wall, and with the comparatively large threaded hole It through its opposite edge wall, of the cutter-levers D D and the adjusting-levers C C having the thickened and rounded intermediate portions fitted in said recesses I), and pivotally connected thereat with the handle-levers, and having their arms G rearwardly extending into said handle-cavities and provided at their ends with the worm-segments g, and the worms I I, having the inner end journals 72/ fitted in said holes 3' positioned transversely of the handle-lever and with their threaded portions within the cavities thereof and in engagement with the adjusting-lever worm.-segments, having the outer and round journal portions 71,, and the squared extremities t and the nuts K, screw-engaged in said holes .7 and having axial ournal-holes for the said j ournal portions 72 of the worms, substantially as shown.
